Capture anomalies while using time series measurement to monitor power lines
Simultaneous time series monitoring for RMS fluctuations, voltage fluctuations, harmonics fluctuations, and flickering
RMS fluctuation, voltage fluctuation, harmonic fluctuation, and flicker (IEC and ∆V10) time series data is
displayed on the TIME PLOT screen. In addition to cursor measurement, you can enlarge events that occur in
the voltage fluctuation event screen if a voltage dip, swell, or instantaneous interruption event occurs during
the measurement period.
Simply set the interval and start time series measurement to display events in the fluctuation graph
Time series fluctuation results are displayed in the TIME PLOT screen
Continuous data calculation processing of all data without fail!

All measurement results are automatically recorded

Calculation method for measured data
-1. RMS fluctuation (dual screen display selection)
-2. Voltage fluctuation (interval and event displays)
-3. Harmonic fluctuation (harmonics and inter-harmonics displays)
-4. Flicker (graph and list displays)
-
1. RMS fluctuations/Harmonic fluctuations : Values are calculated continuously
every 200 ms. The maximum, minimum, and average values are those applicable within the
specified interval.
-2. Voltage fluctuations : Values are calculated for a single waveform shifted by a half wave.
The maximum and minimum values are those applicable within the specified interval. Detailed
measurement of voltage fluctuations is possible because values are calculated every half wave.
-3. Flicker : Values are calculated in accordance using calculation methods defined in the
IEC and ∆V10 standards.
• Pst and Plt measurement conditions according to IEC standards
• ΔV10 measurement (according to Japanese domestic guidelines)

n addition to displaying the various measurements in fluctuation graphs, the 3196 also displays the maximum,
minimum, and average values for each specified interval.
Further, when the 3196 captures a power anomaly, an event marker appears in the upper part of the graph.
